Between the standards B is 10- The invention consists, further, in certain cated a guide-plate d, which is provided with details of construction by which the parts reperforations for the straight lower ends or ferred to are operated at the proper time, shanks l of a plurality of upright heddle-lifts 5 and, lastly, in the special construction of the Z, each of which is formed, preferably, of a needles and heddle-lifts, as will be fully dedoubled-up spring-wire, that is twisted at its scribed hereinafter, and finally pointed out in lower portion so as to form the straight shank 5 the claims. Z, an eye Z being arranged at the lower end of said shanlgwhile the upper ends are bent so as to cross each other and formed with inwardly and downwardly curved hooks F, as shown clearly in Figs. 12 and 13.

To the sides of the standards B B are attached transverse vertical guideplates E, which are provided with rows of perforations for guiding as many horizontal double-ended needles F as there are heddle-lifts, each needle being made long enough so as to project at both ends beyond the perforated guideplates E. Each of the needles F is provided with an elongated loop f, which is bent up from the wire of the needle, as shown in Fig. 14:, and which is arranged at relatively different points in the needles, so that each needle engages its respective heddle-lifts Z, as shown in Fig. 10. The heddle-lifts are so arranged andconnected with their needles that there is no interference of one lift with the other, so that when the heddle-lifts are lifted, as shown in Fig. 10, they move easily up and down in the loops of the needles, but remain always in engagement with the same.

The upper ends of the heddle-lifts Z are guided by stationary cross-bars e e, that extend parallel with the guide-plates E from the front to the rear standards B B, as shown clearly in Fig. 10. The cross-bars e e correspond in number with the transverse rows of heddle-lifts, so that the heddle-lifts are guided during their vertical motion by their lower ends or shanks in the lower guide-plate d and by their upper ends in the loops of the neodles and by the cross-bars c 6-, so that they are reliably guided during the up-auchdown motion imparted to them. To the eyes Z at the lower ends of the shanks l of the heddlelifts Z are attached a corresponding number of heddle-lifting cords or wires l, by which the connection with the individual heddles of the loom is made in the usual manner. From-each side of the upright standards B B extend, about midway of the same, horizontal bracket-arms B, on which are guided by slide-plates g g two card-carriers G G, that are arranged parallel with the needle-guide plates E and on a level therewith, one on each side of the upright standards. The card-carriers G G are made of square cross-section and provided in their faces with a plurality of perforations or holes, which correspond in number and are adapted to register with the projecting ends of the horizontal needles F. The card-carriers G G are also provided at the ends of each of their faces with projecting studs for engaging corresponding holes in the ends of the cards and imparting a positive feed to the same.

The card-carriers G G are su pported at their ends by means of suitable gudgeons g in socket-shaped bearings g of sleeve-shaped supports G, which are supported at their lower ends by the slide-plates g on the horizontal brackets B and provided at their upperends with upwardly-extending adjustable guide-lugs g that are connected by transverse brace-rods 9 The sleeve-shaped supports G are guided on horizontal rods G which are permanently secured to sockets s on the upright standards B B and provided at their outer ends with enlarged heads g To the outside of each sleeve-shaped framecarrying support G is pivoted a link g", which is pivotally connected at its inner end to the lower arm of a bell-cran k lever g that is fulcrumed to the upper part of the standard B, and to the upper arm of which is pivoted a pendent lever-rod g that is recessed at its lower part so as to engage a pin 11, projecting from a frame I, from which the guide-plate d for the shanks of the heddle-lifts is suspended, as shown in Fig. 7. The pendent lever-rods g of the lever mechanisms of both card-carriers G G are located sidewise of each other and engaged at their outer edges by antifriction-rollers g applied to a shifting bar g, which is guided at one end along a fixed pin g on the upright standard B, while its opposite end is pivoted to the upper end of an oscillating link g the lower end of which is pivoted to a stationary hanger 9P of the standard B, as shown in Figs. 2 and 3. The horizontally-shifting bar 9 is intermittent-1y actuated by a pattern-chain mechanism, so as to move either one of the pendent lever-rods 9 into engagement with the pin 71 by their recesses g which are located adjacent to each other, as shown in Figs. 1 and 4. The parts described are duplicated on each standard B, the pins 6 of the frame I being connected by links 2" with the ends of an actuating lever-frame G which is fulcru med to the rectangular base-frame A, and which is operated in the usual manner from the driving camshaft of the loom. By the oscillating motion of the lever-frame G the links 7; raise or lower the pinsz' and frame I and simultaneously therewith the lever-rods g which are at the time in engagement with the pins 1', so as to operate by the intermediate lever mechanism the sleeve-shaped supports of one of the card-carriers and move it with its cardchain 0 on the same toward the adjacent ends of the needles F, so as to produce the entering of the ends of some of the needles into the holes of the card and card-carrier registering therewith and the shifting of the remaining non-registering needles by the action of the non-perforated portions of the card in the needle guide-plates.

From the under side of the sliding supports G of the card-carriers G are suspended, by means of screws 01, U-shaped hangers n, which carry at their lower ends a transverse rod n along which the card-chain ,O is guided away from the card-carrier. A second rod 02 parallel with the rod 71*, serves to guide the card-chain 0 toward the card-carrier. The individual cards of each card-chain O are retained on the top face of each card-carrier G by means of a wire guard N, which is attached at its lower ends to the transverse rod 01 extended in upward direction along the inner 'ing motion of the lever-frame H.

face of the card-carrier, and then bent at right angles thereto over the top face, forming upwardly-curved lips n at the ends of the angular portion, that are connected by a transverse portion of, as shown in Figs. 8 and 9. The ends of the rotary card-carriers G are engaged by catch-hooks N, which are pivoted to braces N of the standards B B slightly above the level of the top faces of the card-carriers G and which engage during the outward motion of the card-carriers the corners of the same, so as to turn them against the tension of the wire guards N for a quarter of a rotation, the overturning being prevented by the binding action of the angularlybent top portion on the corners of the card-carriers. The wire guard N serves to retain the card carrier in posit-ion and to bind on the cards on the inner and top faces thereof, while the studs at the ends of each card-carrier serve to hold the cards in proper registerwith the holes in the faces of the card-carrier and with the needles. The lower portions or shanks of the wire guards N are preferably bent in the form of a coil a as shown in Fig. 8, by which the spring action of the upper angular port-ion is increased, and thereby the turning of the card-carrier and its locking in position when a quarterrturn is made is effectively and reliably accomplished.

A second U-shaped lever-frame H is fulcru med to the same fulcra as the lever-frame G and oscillated by the driving mechanism of the loom. Its inner slotted ends are connected by upwardlyextending pivot-links h with studs it, that are clamped to the upper ends of guide rods 7L2, which are guided in sta tionary guide-sleeves h at the inner faces of the standards B, so as to follow the oscillat- To the upper partof the guide-rods 72, is rigidly at tached by sleeves 71 a knife-carrying frame H of oblong shape, which moves up and down with the guide-rods 7L2. At oneend of the frame H is arranged a laterally-shiftable bar H which is guided by means of slots 7% on screws 7L5, shown in Figs. 10 and 11, said shifting bar being provided with dovetailed recesses Nit-hat are made larger at their lower portions. The rectangular frame H supports a number of parallel lifting-knives H which are pivoted at their ends to the frame H and which are located in the dovetailed recesses h of the bar H The laterally-shiftable bar H serves forthe purpose of tiltingthe lifting-knives, so that they assume elther an inclination to one side or the other of a vertical line passing through their pivots for the purpose of engaging either one hook or the other at the upper ends of the heddle-lifts, and produce thereby the raising of a number of heddle-lifts corresponding to the number of needles that have entered into the holes of the card at the time on the inner face of one card-carrier or the other. A headed stud h is located at the center of the shifting bar H and engaged by the forked upper end of an oscillating lever H which is pivoted at its lower end to the lower stationary guide-sleeve k of the guiderod k and which is connected at its middle portion by a pivot h with a horizontal pushrod H that is guided at its ends like the needles in holes of the perforated needle guideplates E, as shown in Fig. 2 and in plan view in Fig. 3. When either card-carrier G is moved against the ends of the projecting needles and the end of the push-bar H this red is shifted by the pressure of the card-carrier, so that it oscillates thereby the lever H ,which by its forked end produces the horizontal shifting of the bar H and by the inclined faces of the recesses of the latter the oscillating of the pivoted lifting-knives H into inclined position, as shown in Fig. 11, so that they engage during the ascending motion of the frame H as imparted by the guide-rods b the hooked upper ends of all the heddlelifts the needles of which are in the holes of the card and lift them in the loops of the needles, as shown in Fig. 10. When the opposite card-carrier is acting by its card on the needles and knife-governing rod H the lifting-k nives are tilted in the opposite direction. Simultaneously the needles which do not register with the holes of the card press one of the hooks of their heddle-lifts sidewise and out of engagement with the lifting-knives, so that only the heddle-lifts of those needles which are in the perforations of the card and whose hooks are not shifted are engaged by the lifting-knives and lifted, and thereby the heddles connected therewith. The recessed bar H and the lifting-knives H and the pushrod H by which the shifting of the bar H and the tilting of the knives are accomplished, produce the reliable selection of the proper heddle-lifts, so that they are lifted under the influence of the ascending motion of the lever-frame H. The lifting-knives, in connection with the construction of the heddle-lifts and the loops of the needles, form the essential feature of novelty of this jacquard attachment for the reason that this construction permits the ready removal of any one of the heddle-lifts or any one of the needles and the replacing by a new one and its connection with the heddle by the proper wire or 'cord without necessitating the stopping of the loom for any great length of time, as was required heretofore when repairing any one of the needles or heddle-lifts in the jacquard attachments heretofore in use.

The oscillating motion of the lever-frame G serves for the purpose of actuating the lever mechanisms by which one or the other of the card-carriers is reciprocated toward or away from the needle system in connection with the recessed pendent rods g which engage the pins dot the frame I. The oscillations of the pendent rods 9 and the engage ment of either one with the pins 2' is accomplished by the horizontally-shifting bar 9 under the influence of a pattern-chain P, which is shown in Fig. land in detail in Figs.

4, 5, and 6. The pattern-chain P is operated at each up-and-down motion of the frame I by a spring-actuated pawl i that is pivoted to said frame and held in engagement with a ratchet-wheel 71 that is keyed to a shaft 2 which is supported in suitable bearings of the front standard B and a second shorter standard i Alongside of the pawl 11 is hung to the pivot of the pawl a second spring-actuated pawl 2' This pawl is placed in engagement with a second ratchet-wheel i that is not keyed to the shaft i but to a sleeve i", which turns loosely on the same and which carries at its opposite end a triangular stud- Wheel 11 of triangular shape, that serves to engage a spring-pressed lever-rod 2' the upper end of which is connected with one end of a helical spring 71 that is applied at its opposite end to a pin on the horizontalshifting bar g, as shown in Fig. 4. To the shaft i is keyed a sprocket-wheel 11 around which and a guide-wheel 2', the shaft of which is supported by bearings of the standard B and a second short standard 01 at some distance from the shaft 2' the pattern-chain is guided, as shown in Fig. 4. The pattern-chain P is composed of a number of open and closed links, the latter carrying projecting studs or pins p, as shown in Fig. 4. The sprocketwheel of the pattern-chain P is moved under the influence of the pawl t and ratchet-wheel i at each up-and-down motion of the frame I. The projecting studs or pins 10 of the closed links of the pattern-chain P act on a spring-actuated lever-arm 10, that is pivoted to sleeves on the supporting-frame A, it being connected by an upwardly-bent arm 10 with the pawl '5, so as to release the same from its ratchet-wheel 2' whenever one of the pins p moves the lever-arm p sidewise. The sidewise motion of the lever arm p produces instantly the release of the pawl 77 from the ratchet-wheel 11 so that the intermittent rotary motion imparted to the triangular stud-wheel 2' produces the dropping of the angular middle portion of the lever-arm 2' into the depression of the stud-wheel 7J so that the shiftable bar g is returned under the influence of a second helical spring g, attached to it and the front standard B, from the position shown in Fig. 4 to the position shown in Fig. 1 until the bar g is arrested by the pin g When the lever-rods g are in the position shown in Fig. 4, the right-hand card-carrier G is operated and moved against the righthand cards of the needles, while when the lever-rods g are in the position shown in Fig. 1 the left-hand card-carrier is actuated and moved against the left-hand ends of the needles. In the former case this returns the helical spring 2' in its contracted position ready for the next oscillating motion of the lever-arm't' when the next shifting action of the bar toward the left is required. During the return motion of the shifting bar g by the action of the pin 19 on the pattern-chain and the lever-arm p the oscillating lever-rods g assess which are under the influence of antifriction rollers on the bar g, are shifted into the position shown in Fig. 1, so that the pin '5 enters into the recess of the left-hand lever g and that by the next downward motion of the lever-arm G under the influence of the pin t", the left-hand lever g is actuated, and thereby by the intermediate mechanism the left-hand card-carrier moved forward with its card-chain toward the needles. As this card-chain controls the cards that produce the ground between the figures of the fabric, while the opposite card-chain produces the figures one of the ground-cards is placed in position for the system of needles and heddlelifts. When the ordinary links of the pattern-chain pass over the lever-rod p, they exert no action 0n.the same, and consequently do not release the pawl '6 from the ratchetwheel i and the same is thereby operated by the vertically-reciprocating frame I, so as to imparta rotary motion to the triangular studwheel i which by its projecting stud operates the lever-rod 1' and produces thereby the shifting of the bar g whereby the recess of the right-hand lever-rod g is placed in connection with the pin 71, so that by the downward motion of the card-carrier frame G and the intermediate lever mechanism connected with the right-hand lever q the right-hand card-carrier carrying the figurecards is moved up against the right-hand ends of needles so as to operate the needles and heddle-lifts and produce thereby the proper lifting action on the figure-controllin g heddles.

The shaft i as well as the sleeve t", are each provided with a disk 2, which are acted upon by the free ends of flat friction-springs t", that exert the required friction thereon, so as to prevent the irregular turning of the. shaft i or of the sleeve 2'", and secure the regular movement of the pattern-chain under the influence of its actuating mechanisms.

The operation of my improved jacquard attachment is as follows: When the parts are in the position shown in Figs. 1 and2, the pattern-chain and the shifting mechanism operated thereby have placed the pendent leverrods 9 in such position that the left-hand lever-rod is engaged by the pin 1' of the frame I. The upward motion of the inner leverframe G by the action of the loom produces then, by the intermediate lever mechanism connecting it with the left-hand or ground card-carrier, the horizontal inward motion of said carrier on its guide-brackets 13 toward the left-hand ends of the needles. Simulta neously therewith the frame I is lifted, together with the guide-plate d,suspended therefrom, the guide-plate (1 raising all the heddlelifts which are supported thereon, so that their hook-shaped upper ends pass beyond the lifting-knives. By the action of the card on the ends of the needles those needles which do not enter into the perforations of the card and card-carrier are moved toward the right,

also the horizontal push-rod H by which the lever-rod H and the shifting bar H of the lifting-knives are operated. The heddle-lifts of those needles the ends of which enter into the holes of the card and card-carrier are not changed, but remain in their normal position; but the heddle-lifts of those needles which are shifted laterally are acted upon by the loops of their needles in such a manner that their right-hand hooks Z are moved toward the right into the position shown in Fig. 13. Simultaneously the lifting-knives are tilted toward the right by the shifting bar H as shown in Fig. 11. As soon as the shifting motion of the needles and the tilting of the lifting-knives are accomplished an upward motion is imparted to the lifting-knives by the frame H under the influence of the fulcrumed leverframe H, so that the lifting-knives engage the hooks of all those heddle-lifts the needles of which have entered into the holes of the card and card-carrier, while the hooks of the heddle-lifts that were acted upon by the shifted needles are moved sidewise clear of the lifting-knives, so that they cannot be engaged by the same. Consequently the heddles that are suspended from the raised heddle-lifts are lifted and the shuttles forming the ground are thrown on the downward motion of the frame I under the influence of the lever-frame G while the pattern-chain is operated by the pawl-and-ratchet mechanism actuated by said frame, so that the next link of the patternchain is presented to and placed'in contact with the oscillating arm by which the shifting bar 9 of the pendent lever-rods g is operated. When the next link of the patternchain is again a link which controls a groundcard, the left-hand card-carrier which has been moved in outward direction again by the downward motion of the lever-frame G is again moved in toward the left-hand end of the needles and the heddle-lifting operation repeated. During its outward motion of the card-carrier it is turned on its axis by the hooks N through an angle of ninety degrees, and thereby a new card presented to the ends of the needles, the heddle-lifts of which are returned to their normal position by the downward motion of the frame I and guide-plate (1 under the action of the lever-frame G while the lifting-knives are returned by the downward motion of the frame H and lever-frame H. The new card acts then again on the lefthand ends of those needles in the same mannor as before, so that the ground-forming heddles are again lifted and another pick of the ground-forming shuttles made, and so on as long as links controlling the ground-cards are moved forward by the pattern -chain. lVhen, however, a link with a projecting pin or stud is placed by the pattern-chain into contact with the shifting mechanism by which the pendent lever-rods g are operated, they are moved toward the left, so that the recess of the right-hand lever-rod g is placed in en- 7 gagement with the pin 1', and thereby by the upward motion of theinner lever-frame G and the intermediate lever mechanism the righthand card-carrier moved inwardly toward the right-hand ends of the needles and the knifeshifting push-rod. The lever-frame G lifts at the same time, by the frame I and guide-plate d, all the heddle-lifts supported by the latter. Ihe card on the card-carrier receives the ends of all those needles that are in register with the holes in the same, while those needles which are not in register are shifted toward the left, so that the left-hand hooks of the heddle-lifts are moved by the shifting needles toward the left. Simultaneously the liftingknives are tilted toward the left and placed into engagement with the left-hand hooks of the unshifted heddle-lifts, whereby the latter and their heddles are lifted and the shuttles thrown for forming a portion of the figure of the fabric. By the downward motion of the lever-frames G and H the right-hand carrier is moved again in outward direction, and the needles, lifting-knives, heddle-lifts, and beddies are returned into their normal position. By the next actuation of the pattern-chain, due to the downward motion of the frame I and the pawl-and-ratchet mechanism operated thereby, the pin t is placed again into engagement with one or the other lever-rods g so that the operation before described is repeated, and so on, according as the links of the pattern-chain actuate either the cardcarrier carrying the ground-cards or the cardcarrier. carrying the figure-card and bring them up to the needles for producing the throw of the corresponding shuttles.
